Functional Diagram

General Description

The HMC385LP4 & HMC385LP4E are GaAs InGaP

Heterojunction Bipolar Transistor (HBT) MMIC VCOs

with integrated resonators, negative resistance

devices, varactor diodes, and buffer ampliﬁers.

Covering 2.25 to 2.5 GHz, the VCO’s phase noise

performance is excellent over temperature, shock,

vibration and process due to the oscillator’s monolithic

structure. Power output is 4.5 dBm typical from a

single supply of 3V @ 35mA. The voltage controlled

oscillator is packaged in a low cost leadless QFN

4x4 mm surface mount package.
